BEARING Flled April a 1922 'athis/w14 l Application filed April 8,'

To (t/#whom it may conce/rn.:

Beit known that we., nminn ERDAHL and, HENRY -linigis-HL. citizens of the United Stat-es, residingy at Britton,l in the county of, Marshall and State of South Dakota, have? invente-d certain new and useful vImprovements-tin Bearings, ofwhich the' following is a=speciication.

This invention relates -toL bearings, and more particularlytol adjustable bearings Anobjectof the invention is the provision of abearingwhich may be adjusted or set up without; removingfthe bearing caps.

A fui-tli'efobject is e provision of a wedge adjust-ing member to permit tight ening of the bearing without disassembling.

In the present invention, -we employ a pair Aof Wedges arranged between the bear- A ing member and the cap, and a separating Wedge adapted to move said wedge members to tighten the bearing when the separating Wedge is moved inwardly.I Any suitable mechanism may be employed for controlling the separating Wedge.

In the accompanj ng drawings, we have shown one embodiment of our invention. In this showing: j

Figure 1 is a side elevation of a bearing showing a shaft in section, l i

Figure 2 is a vertical sectional view of the bearing,

Figure 3 is a transverse sectional view on line 3--3 of 'Figure 2, and,

Figure 4 is a detail view of parts of the bearing removed.

Referring to the drawings, the reference numeral 1 designates a shaft, and 2 a connectingv rod adapted to be secured thereto. The upper half of the. bearing cap is carried by the connecting rod in the usual manner, as indicated at 3, and is provided with the usual flanges 4. A lower bearing cap 5 having flanges 6 is adapted to be se'- cured to the connecting rod by means of bolts 7, passing through openings in the flanges 4 and 6. The bolts are retained in position by means of nuts 8. The upper bearing cap is of the usual construction and a bearing member 9 is arranged between the cap and the shaft.' A similar member 10 is arranged between the. lower cap and the shaft and this member is adjustable by means of suitable Wedges which may be moved inwardly and outwardly to force the bearing member toward the shaft, or per-v mit it to be Withdrawn. show-n, the in-` "sputtering-Dani.

ner face ol' the lower bearing cap is provided witlna circular `roove 1l extending from fiange to flange and taperingv toward the bottom. The bottom of the groove coinY Amunicates with a radial `groove l2 and an vgroove. lThe radial n'roove is substantially rectangular -in shape.

` A pair of bearingwedges are arranged in the circulargrooves ll. As shown, these members taper vfrom line edge 14 at. their upper ends to a rela tively thick lower end A153. .Each of the bearing wedges is provided with a rib .16 on its lower face adapted to be received in one ofthe groovesll. The lower end of the rib is provided with an inclined face' 17.

A separating wedge 18 is adapted to be arranged in4 the radial groove 12. This wedge is substantially rectangular in cross section and is provided with a pair'of beveled or inclined faces 1S) adapted to engage the inclined faces 1T of the bearing wedges. An adjusting screw or bolt. 2() is arranged in the opening` 13 and is provided' with a nut 21 which is received ina recess in the lower face of the separating Wedge. This screw maybe retained in adjusted )osition by means of a lock nut 22. Spring s ims 225 may be arranged between the flanges of the bearing cap. As shown, these sliims are provided with openings 24' for the passage of bolts 7 and their inner ends are split, as at 25.

When a splash system of lubricationl .is employed, the lower bearing cap is provided with an opening 2G adapted to aline with an elongated opening 27 in the bearing wedge. The bearing member 10is provided with an opening and a: tubular member 28 is passed through these openings. The tubular member is provided with a grooved edge 29 adapted to more readilypicknp oil and feed it to the bearing. lVhen a force feed lubricating system is employed, the ends of the spaces 25 are closed byplates 30, adapted to be secured to the ends of the shims in any suitable manner.

The operation of the device is as follows:

.and t e operation is completed.I The bearing may be tightened a any time byv merely loosening the lock nut nd turning the bolt without removing the bearing cap, as is necessary at the present time. I

It is to be understood that the form of our invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit 0f the invention or the scope of the subjoined claims.

Havlng thus described our invention, we claim:

1. An adjustable bearing comprising a pair of complementary members each having a substantially semicircular bearing member mounted therein, oneA of said complementary members forming a bearing cap, shims mounted between said complementary members and having their inner edges arranged between and contacting with the longitudinal edges of said bearing members, the inner edges of said shims being split longitudinally, and .meansfor adjusting the bearing member df the bearing cap. 2. An adjustable bearing comprising a. pair of complementary members each havmg a substantially semicircular bearin member mounted therein, one of sai complementary members forming a bearing cap, shims mounted between said complementary members and having their inner edges arranged between and contacting with the longitudinal edges of s aidkbearing members, the inner edges of said shims being split longitudinally, a pair of wedges arranged between said bearing cap and its bearing member and havin their inner edges-arranged adjacent eac other, said wedges having arcuate eccentric inner and outer faces and being thickestv at their' adjacent edges, andy means for separating the adjacent edges of said wedges.j

In testimony whereof we affix our signatures in presence of two witnesses.
